What if I told you a balloon could fill up with air, without you having to blow it up? Sounds crazy right? But it’s true! With a little chemical reaction a balloon can fill with air without the manual labor of blowing it up!
What you’ll need
- Baking Soda
- Funnel (found this to best way to limit the mess!)
- Empty Bottle
- Latex Balloon
Chemical Reactions and Filling the Balloon
Using the funnel, put about a tablespoon of baking soda into the latex balloon. Rinse out the funnel and use it to fill up the bottle about a third of the way with the vinegar.
Place the balloon over the mouth of the bottle, making sure not to get the baking soda in the bottle just yet. When it is securely around the mouth of the bottle, lift the balloon and empty the contents into the bottle and watch as it fills up with gas due to the chemical reaction!
How does it work?
Baking soda reacts with the vinegar to create carbon dioxide gas! This kind of reaction is called a chemical reaction, and they occur when two or more substances react together to make one or more different substances. When the two react to make carbon dioxide gas, which fills up the balloon!
You can see the reaction happening as the baking soda dissolves in the vinegar you will see it bubble up. Those bubbles are full of the carbon dioxide gas which fill . This is the same reaction that happens when you make a volcano!
